SOAP header problem

Question

I have just started looking into Oracle BPM, and have come across a problem, to which I can't find an answer in this forum or elsewhere on the net.
I have created a very simple process with one automatic activity which should just call a web service and return the result.
We use custom SOAP headers in our services, but the WSDL import in BPM Studio has recognized the header definitions and generated the corresponding types.
However, when I attempt to call the service, I get an error because of some invalid header attributes added by the BPM web service client.
I use this code to set up the service:
kontaktSvc as Nykredit.Kontakt.KontaktService = Nykredit.Kontakt.KontaktService(wsConfig)
requestorIdentity as Nykredit.Kontakt.RequestorIdentityType
requestorIdentity.tagName = "RequestorIdentity"
requestorIdentity.requestUID = "qwerty"
requestorIdentity.requestTime = Time()
logMessage "RequestorIdentity: " + generateXmlFor(requestorIdentity)
kontaktSvc.requestHeaders[] = requestorIdentity
The logMessage statement tells me, that the RequestorIdentity header is OK:
RequestorIdentity: <?xml version="1.0" encoding="UTF-8" ?>
<ns1:RequestorIdentity xmlns:ns1="http://technical.schemas.nykreditnet.net/header/requestoridentity/v1" >
     <ns1:RequestUID>qwerty</ns1:RequestUID>
     <ns1:RequestTime>2010-01-22T11:54:13.352000+01:00</ns1:RequestTime>
</ns1:RequestorIdentity>
However, my service fails because of some header attributes, that do not show up in the logMessage.
The SOAP request which is received by the service looks like this:
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Header>
<ns1:RequestorIdentity
mustUnderstand="0"
actor="http://schemas.xmlsoap.org/soap/actor/next"
xmlns:ns1="http://technical.schemas.nykreditnet.net/header/requestoridentity/v1" >
     <ns1:RequestUID>qwerty</ns1:RequestUID>
     <ns1:RequestTime>2010-01-22T11:54:13.352000+01:00</ns1:RequestTime>
</ns1:RequestorIdentity>
</soapenv:Envelope>
As you can see, the BPM web service client implementation has added the 'mustUnderstand' and 'actor' attributes, but they have no namespace prefix, which makes the request invalid.
Obviously, the header attributes should be prefixed with the 'soapenv:' namespace prefix to be valid.
Now the question is: Is this a bug or am I doing something wrong here?
I really hope you can help me, since this is quite a showstopper right now...
TIA

Hi Stephen
I am Peters colleague who patched the old Axis library.
I checked out the cource code for Axis version 1.2.1 from http://svn.apache.org/viewvc/webservices/axis/branches/AXIS_1_2_1_FINAL/java/
Then I commented out some of the contents of org.apache.axis.message.SOAPHeaderElement.outputImpl() from line 225 to 245.
Finally I built the whole thing using the supplied build.xml.
The effect of the patch is, that the ‘actor’ and ‘mustUnderstand’ attributes are never generated, so the patch will not work if these attributes are actually needed.
Since we don’t use the attributes, it works fine for us.
The proper fix of course, would be to assign the right namespace prefix to the attributes.
